Somewhere in a book Plato himself laments that texts are not interactive enough, when one interacts with them one has the desire for advice on action. So if essays aren't cutting it in schools and books aren't the pinnacle of learning then we should respectfully move on.<p>I disagree that experts will be the starting point for the next "medium" after books, they still have too much cruft to blast away if you are going to benefit anywhere near as much as they did from the concepts. The new knowledge will be much more synthetic and symbiotic.
